Period Before It Is Due And Mucus Red What Are The Reasons Why Women May Bleed Brown Blood Before Their Period Is Due?

What are the reasons why women may bleed brown blood before their period is due? - period before it is due and mucus red

my term is not due to come for at least a few days a couple of days, but must be by the end of the week. Yesterday and the day was by the letter of discharge Brown, Goo Brown, identified stick, sticky mucus, clear and not red or dark red than normal. I have an infection and no smell. That has never happened before, and I swore that after my time, because I was still cramping as if I have less pain. Why?
